Tandem Scratch

To simultaneously and unselfishly scratch in a relaxing manner, the inside of each others forearms. When one is scratching, the other simply extends fingers so as to scratch the partners arm as well. Everyone is a winner.

Lying on the sofa trying to stay awake while watching Disney films, one extends arm onto partners lap, Tandem Scratch takes place and therefore both are getting even attention!

Tandem Titties

Tandem titties refers to two sets of titties in close proximity of one another such as two nude women hugging. Or two girls in bikinis with their titties touching. It can also be referred to a threesome when there is one man and two women.

"I got a great pic of some tandem titties on the boat last night!"

Tandem Bikers

One of those irritating couples that think they have to do everything together. Often won't hang out because their fellow biker has already made their plans for them. They may also coordinate outfits. The name suggests that they even choose their mode of transportation to feed their habits.

Ryan had to check with his girlfriend before he could RSVP, so I doubt he'll show. No doubt she already has plans for him to watch the Bachelorette or something. Fucking tandem bikers.
